Effective Lagrangian for Nambu-Goldstone modes in nonequilibrium open systems
Masaru Hongo, Suro Kim, Toshifumi Noumi +1
We develop the effective field theory of diffusive Nambu-Goldstone (NG) modes associated with spontaneous internal symmetry breaking taking place in nonequilibrium open systems. Th…
Instantons in Chiral Magnets
Masaru Hongo, Toshiaki Fujimori, Tatsuhiro Misumi +2
We exhaustively construct instanton solutions and elucidate their properties in one-dimensional anti-ferromagnetic chiral magnets based on the nonlinear sigma model descript…
Anomaly-induced transport phenomena from the imaginary-time formalism
Masaru Hongo, Yoshimasa Hidaka
A derivation of the anomaly-induced transport phenomena---the chiral magnetic/vortical effect---is revisited based on the imaginary-time formalism of quantum field theory. Consider…
Phase structure of the twisted flag sigma model on
Masaru Hongo, Tatsuhiro Misumi, Yuya Tanizaki
We investigate the phase structure of the compactified -dimensional nonlinear flag sigma model with respect to two -terms. Based on the circle compactification…
Fate of spin polarization in a relativistic fluid: An entropy-current analysis
Koichi Hattori, Masaru Hongo, Xu-Guang Huang +2
We derive relativistic hydrodynamic equations with a dynamical spin degree of freedom on the basis of an entropy-current analysis. The first and second laws of local thermodynamics…
